To all whom it may concern:

it known that I, BfiLA-TOMIQ\Y, acitizen of Hungary, residing Gary in the county 01" Lake-and State of Indiana, have invented certainnew and useful Improvegenerally an object to-provide a novel toy of thissort. p

A furth'er object of the invention isto providea' novel arrangement by which'theaeroplane is inserted into the projector with its wings and tail'collapse'd' or folded, the same being causedjto expand or unfold when released from the projector. V

. For further comprehension ofthe invention, and of t'h e objects and advantages thereof, references will be had to the following description. and accompanying draw iirgs,' and to the appendedelaiins'in which the variousnovel features of the invention are more particularly'setforth.- Fig. 1 01"? the drawingsis aside view of the aeroplane asi'it emerges from'the projector. Fig; 2 is a side View otthe aeroplanejiwith wings extended. I

Fig. '7 is a vertical section on the line 7'? of Fig. 6 and at right angles to the latter.

Fig. 8 is a similar View to Fig. 7 but showing the plunger extended. 7

Referring now to Figs. 1 to of the draw-- ings. the aeroplane which I have devised to he shot from the proiector comprises two pairs of rigidly constructed wings 10, 10 and 11, 11 which extends at right angles to one another, the wings 10 being located at a distance above the Wings 11. The Wings 10 are rigidly fixed on arms 12 pivoted to a hori zontal bar 13 Which is supported at its ends bydiagonal struts l l extending upwardly and' outwardly from a central post 15 to wlnchthebar. lSis-also rigidly connected midway. between'its ends: This central post 15" serves as-the means for mounting the aeroplane on. the projector, as will be presently pointed (out; These arms 12 have counterweights l6 fixeditheretoand acting to hold the wings in extendedv position:

l hen the wings are in the v'ert1cal, orfolded, position shown'm Fig. 1 these weights are dead centered above the bar l3. At tached at opposlite ends to the inner en'ds of the wingslO and the top or the postl5 are comparatively light elastic cords 18:

The wings lliare fixed on arms 20 pivoted to a bar 21 which -:is connected to post 15 in a li'lre ni'anner to the bar 13,-} nd supported at its ends by aframe 22 mounted on the post? The: arms 20 have" counter-weights 28 fixed thereto an'd acting similarly tothe counterveights 16. To give these wings ll an initial 3 movement to extended positionli ght elastic cords 2 l'ar'e attarhed thereto and to theends ofbar l3i V Journaledjin suitable brackets Qfifixed to andungler -the wings 11' is a pair-of shafts 27 whi L ldiagonallywith respect to the wings shown in' Fig5 3. These shafts have propellers 280i ordinary lielical con st'rrictionfixed-totheir outer ends and are adapted to be rotated by elongated paddle wlreelsflfl'fixed th'ereo'n under the wings 11, one side ofthe's'e wheels 29'reg-iste'ring with slots 'O'cut verticallfy' througli the'wings 1.1.1

- The" projector from which the aeropl anc propelled comp'risesan elongated box 40 which may compriseftwoparts hinged together-"as at 40'. Extending longitudinally inthis box is a plunger 41 preferably made of two parts screwed .ogether as atell'; one end oi this plunger p ojectingiroin the upper end of the box and being provided with soclret l l to receive the lower end of post 15. The inner end of the plunger 41 is secured to a orosshead 14 having projecting fingers 45 guided .in slots 46 in the sides of the box 40. Secured to this crosshead H, and to the upper end of the box .410, are elastic cords 47 which constitute the propelling medium. Mounted in the lower end of the box 41.0 is a latch 48 adapted to enthe crosshead 44c and hold the elastic cords tensioned. This latch is of hell crank shape and has an upwardly extendingarm adapted to engage an eye element 50 on the erosshead 4d, the other arm of the latch pr0- -jecting laterally and being adapted to be engaged by a. cam disk 51 fixed on'a rod 52 rotatable in the box 40 to release thelatch 48, this rod having a knurled head 53 for rotating purposes.

In the use of the toy the plunger 41 of the projector is drawn back, and held by latch 48. The lower end of post 15 is then inserted in the socket-42. hen rod 52is rotated the latch d8 is released and the plunger ll flies outward, throwing theaeroplane up intothe air. While the aeroplane is rising, the pressurerof air on the wings holds the latter in the folded position shown in Fig. 1

but when the aeroplane comes to rest the elastic cords-and counter-weights cause the wings to unfold. 1

As the aeroplane falls toward the ground,

the paddle wheels '29 are caused to rotate,v driving the propellers 28, and by reason of theparticula'r diagonal disposition of the shafts 27, causing the aeroplaneto revolve around the post15, I

When the device is not in use the two parts of the box e0 may be folded'upon one another as shown'in Fig. 5, the top section of plunger 41 being first unscrewedj The 60 being provided on. one'si'de of the box.

"box 4011s preferably of sufficient size to permit the aeroplane, when folded in Fig.1, being inserted in one of the sections of the box for convenience in carrying, a handle The open sides of the two box halves may be closed by sliding doors 61f Latches such:

as 62 may be provided to hold the two parts of the box in either folded'position.

Having thus describedinvention what I claim as new and desire to protect by Letters Patent of the United States is as follows: 7 V V 1. A toy of the type describedcomprising two pairs of pivoted wings extending at right angles to one another and adapted'to be folded to vertical positionor extended to horizontal position, ,means urging said wings to horizontal position, a frame element on which said wings are mounted, and

a projector adapted to engage the frame element, for the purpose specified. 1

2. -A toy of the type described. comprising two pairs ol' pivoted wings extending at right angles to one another and adapted to "be folded to vertical position or extended to horizontal position, eounterweights con nected to said wings to hold the same extended, said counterweights being vertically dead centered with respect to the pivotal axes of thewingswhen the latter are folded, and elastic cords connected to the wings, for the purpose specified. s s V '8. A toy of the type described comprising a post, a pair of horizontal bars fixed at difi'erent heights to said post and extending, at right angles to one another, arms plvoted propellersmounted on the wings and {LP-- ranged to cause the wings toirevolve as a unitaround a vertical axis, and'means whereby movement of airpast sald wingsat right angles thereto, dr ves the propellers, sald means including shafts on which said propellers are mounted, and paddle wheels fixed to said shafts. V i e p 1 f- 6. In a toy aeroplane, :a-pair of oppositely extending wings, horizontal shafts journaled on said wings and extending diagonally thereof, propellers mounted on the outer ends of said shafts, and paddle wheels fixed on said shafts. V J 7.111 a toy aeroplane, a pair of oppositely extendingwings, horizontal shafts journaled on said v wings and extending diagonally thereof, propellers mounted. on the, outer ends'of said shafts, and paddle wheels fixed on said shafts, under. the said wings, said wings having slotsextending therethrough adjacent one side of the paddle wheels.

In testimony whereof I have affixed; my
